Hi all,
I've been operating my Kibana on the same node as my first ES node for a while now. So the first node of ES is running all 3 components of ELK on the same machine.
Recently I wanted to split off Kibana and Logstash onto their own nodes. So that ES would not have to share it's memory with any other applications.
I fired up 3 t2 micros on AWS EC2 and installed Kibana there. I configured it and had all 3 nodes working with my ES setup. They were running in 3 different accounts, so I could stay within the free tier for the first year.
So the interface was identical to the one I had working on the first ES node. After letting them work for a while, if everything was still working, I'd put them behind a load balancer and have some redundancy.
But what I've found after running the 3 t2 micro's all night was that they would get overwhelmed, run out of memory and become inaccessible. Meaning that I couldn't ssh into them, and the kibana web interfaces that I'd seen previously were not available. It'd just be a grey screen.
I'd have to log into AWS, shut down the nodes one by one, and then start them back up again. Then they'd be fine. And then they would run for a while again, before becoming inaccessible again.
So what I'd like to know is if it's possible to tune Kibana to run within the memory available on a t2 micro instance. Which is 1GB.
So in short, is there a way I can get Kibana to run withing 1GB of memory so that I can stay within the free tier on Amazon.
I hadn't gotten around to trying this with Logstash yet, by splitting off Logstash into it's own node(s). I wanted to see if I could get this to happen with Kibana first.
